Possibly pregnant?

Taylor • 01/15/12 💍 && ttc👶🏻#1
For the past couple of days I have been feeling constipated and feeling like I have a sinus infection. It wasn't severe, just mild come and go symptoms. Yesterday, I started feeling cramps with light nausea and headache. Today I'm having sore breast and nipple pain, follow by cramping, headaches, hot flashes, frequent urination, loose stool, indigestion, gas, and nausea. All the symptoms come and go, other than the breast pain. I've always had irregular periods, the beginning of last September was my last period. I do not have any problems, my obgyn says it has to due with my nutrition intake. Last year on September 24th I found out I was pregnant, sadly misccaried at 9 weeks.  My fiancé and I have been ttc since the miscarriage and I'm afraid to take a pregnancy test to find out these symptoms were all in my head. Please positive, helpful comments, opinions, advice, experiences only.
